ABSTRACT:
Catalysts which are soluble in a variety of solvents are prepared by reacting zinc compounds with anhydrides in the presence of an alcohol or by reacting zinc salts with a monoester of a dicarboxylic acid. These catalysts can be added as a solution to a mixture of epoxides and carbon dioxide to prepare polyalkylene carbonates.
